FLY-TRAP.

- Specification of'Letters Patent.

Applicationfiled October 18, 1911.. Serial No. 655,362.

To all whom it may concern Be it known that I, W'ILLIAM J. HAMIL- Thisinvention relates to a new and useful;

fly trap.

The principal object of the invention is the provision of an improveddevice of this nature in which novel features are involved.

One of the features of the invention is the provision of an outer meshwork casing having a smaller removable V-shaped mesh work casingarranged therein and secured to the bottom of the outer mesh workcasing. The V-shaped casing is open at its bottom to permit the flies orother. insects to pass through the inlets.

Another feature of the device is the opening in the bottom of the-outercasing, which 1 opening is provided with beveled edges to prevent theV-shaped casing from entering the outer casing too far, there beinglatches to hold the V-shaped casing in the opening.

Another feature ofthe invention is the novel construction of the meshwork of the V-shaped casing, which will permit the entrance of the fliesor other insects, but not their exit. t

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed. 7 In thedrawings :Figure 1 is a view in perspective of the fly trap constructedin accordance with the invention. Fig. 2 is a longitudinal sectionalview. Fig. 3 1s a transverse sectional view. Fig; 4: is a detailperspective view of the inner or V-shaped casing. Fig. 5 is a bottomplan view of the entire fly trap.

Referring to the drawings 1 and 2 designate the top and bottom of thefly trap. Top and bottom are joined by sheet of wire mesh work 3, thusforming a casing. Sheet metal bands 1 are secured to the top and bottomover the mesh work, as shown. Standards 5 are dovetailed in the top andbottom, one at each end, to hold the same spaced apart. These standardsare extended a short dis tance below the bottom in order to afford legs6, which together with'the legs 7 support the fly trap a short distanceabove any suitable base. The bottom 2 is provided with an opening 8, asshown in Fig. 5. The longitudinal sides 9 are beveled, as shown PatentedMay 28,1912.

in the transverse sectional view of Fig. 3.

The object in beveling these sides, is to afford means to prevent thesmaller V-shaped casing '11 fromentering the outer casing too far, whilethe latches 12 prevent the casing Z ng end pieces 13, which are steppedas shown at 1 1. Areas of mesh work 15 are secured to the edges16 belowthe step portions 14 of the end pieces 13. The upper edges of the meshwork 15 at each end thereof are over the steps 14, as. shown in Fig. 1.Sheets of mesh work bent upon themselves as at 17 are secured totheedges 18 of the end pieces 13; -These sheets of mesh work are designatedby the character 19. The lower portions 20 which are adjacent oneanother of the sheets of mesh work 19 are extended a short distancebelow the upper edges of the areas of mesh work 15, thus forming two ofthe entrance passages 21. The sheets of mesh work 19 at the points wherethey are folded on themselves are spaced apart so as to provide thethird entrance opening for; passage 22.- The portions 23 of the sheetsof mesh work 19 are extended in close positions to the upper edges ofthe areas of mesh work 15, and are flared outwardly, as shown. The endsof the portions 20 of the sheets of mesh work 19 are seated in thegrooves 24: of the end pieces 13. To afford a finish to the innercasing, and to secure the areas .of mesh work to the end pieces- 13,

7 :from falling downwardly out of the open- The inner casing 11 consistsof the two strips of'sheet metall25 are secured to the edges of the endpieces.

'To remove the inner casing from the open ing 8, in order to emptytheouter casing of the flies or other insects a rod 26 connects betweenthe end p'ieces13. .This rod 26 not only affords a hand hold to removethe inner casing but also constitutes means for holding the end piecesfirmly spaced apart.

Natural tendency of flies or similar insects when travelingover anapproximately vertical surface is to always move upwardly, thereforewhen the flies enter the inner V-shaped casing they will either passthroughthe-passages 21 or the opening at theapex of the V-shaped casing,and after once having entered the outer casing they find it difficult toescape, for they hardly ever move downwardly upon a substantiallyvertical surface.

The top of the fly trap is provided with a handle 27, so as to permitthe trap to be moved from place to place.

The invention having been set forth, what is claimed as new and usefulis 1. In a fly trap, an inner trap casing Vshaped in cross section, thetrap casing having end pieces having their side edges stepped, sheets ofmesh work bent upon themselves and spaced apart at the points where theyare bent to form an opening and secured to the end pieces above thestepped portion, the inner portions of said mesh work being extendedbelow the outer portion, while the outer portions thereof are bentslightly outward, areas of mesh work secured to the edges of the endpieces below the stepped port-ions and bent slightly over the steppedportions, the last mentioned areas of mesh work having their upper edgesspaced apart between the inner and outer port-ions of the first meshwork and means for securing the sheets of mesh work to the end pieces.

2. In combination, an outer casing comprising a top and bottom andhaving mesh work sides between them, an inner casing open at the bottomsupported from the bottom of the outer casing and extending inwardlythereof, the inner casing being V- shaped in cross section and havingend pieces having their side edges stepped, sheets of mesh work bentupon themselves and spaced apart at the points where they are bent toform an opening and secured to the end pieces above the stepped portion,the inner portions of said mesh work being extended below the outerportion, while the outer portions thereof are bent slightly outwardareas of mesh work secured to the edges of the end pieces below thestepped portions and bent slightly over the stepped portions, the lastmentioned areas of mesh work having their upper edges spaced apartbetween the inner and outer portions of the first mesh work and meansfor securing the sheets of mesh work to the end pieces, the end pieceshaving grooves, the inner portions of the first mesh work being extendedbelow the upper edges of the first mesh work and secured in the grooveat their ends.

In testimony whereof I have signed my name to this specification in thepresence of subscribing witnesses.
